Worked great until the latest update and now Loop doesn't work properly. I like the new interface and features, but I use this for Looping videos, and it hasn't worked properly since the release and still doesn't. I am going back to an older version for a couple months and hopefully they can get this to work properly.

I can't imagine YT without this add-on!

deixou de aumentar o tamanho do vídeo automaticamente

Δουλεύει μια χαρά. Τα εικονίδια εμφανίστηκαν μετά από επανεκκίνηση του υπολογιστή. Από τις ρυθμίσεις μπορείς να το παραμετροποιήσεις όπως σε βολεύει.

An extension that brings all of the best video player settings from a wide range of different video players and adds them to a player that should have pioneered these options in the first place.

This and "Youtube Watchmarker" are the best Plugins for YouTube!

Used to be a no-brainer add-on, but currently is a huge performance hog that will constantly freeze youtube tabs, so there's a trade-off to make between the great features it offers and having the speed of using youtube in Firefox roughly cut in half.

Update: Turns out the slowness was/is actually a bug with Firefox 86 and later on Windows 8.1 and only affects exactly one computer of mine. It's still a no-brainer add-on.

Everything is great !

Best youtube application out there, amazing stuff

If you spend any time on youtube, you need that add-on.

Yeah what others have said - these latest updates (I'm using 2.0.103.2) when proceeding through a playlist, the first video plays at the preferred resolution, but the "next" video in the list doesn't. I presume it's a bug, hopefully it can get fixed soon?
